Research on Automatic Concept Extraction for Tea Domain Ontology

XU Jicheng,LI Shaowen,ZHANG Youhua,GU Lichuan(School of Information and Computer Science Anhui Agricultural University,Hefei 230036)  
Aimed at reducing the time and labor required in current manual ontology construction,an automatic method of extracting ontology concept was proposed in this paper,based on the knowledge of tea domain.Firstly,tea domain corpus was processed by Chinese word segmentation,and the set of candidate concepts(compound words) was obtained by mutual information technology,and then the ontology concepts of tea domain were automatically extracted by judging the domain coherence of the candidate concepts.Experiment was performed by related prototype system,and the results proved that the method was effective.
